Both directory traversal attacks in general and zip-based versions in specific have been a known thing since the 1990s (if not earlier). It seems absurd that so many (un)zip utilities could be vulnerable to a seemingly-obviou… Continue reading How could Zip Slip go uncaught for so long?
Thousands of software projects and libraries contain code that extracts archives in an insecure way, allowing attackers to write arbitrary files outside the intended directories. In many cases, this can lead to remote code execution. The vulnerability… Continue reading Zip Slip Vulnerability Affecting Thousands of Apps Puts Systems at Risk

Scenario/question:
A unix directory tree has NTFv4 ACLs configured to allow an unprivileged account traversal on all dirs (but no other ACL granting further rights on any file/dir anywhere
In such a case, is it completely s… Continue reading Is the traversal permission in a Unix filesystem exploitable by itself, in the absence of any other permissions/ACLs?
So I’ve been attempting to use dirbuster to fuzz a few vulnerable machines. I haven’t been satisfied with the outputs so I started trying some manual fuzzing and then referencing the default dirbuster wordlist as well as othe… Continue reading Fuzzing a webserver using DirBuster

I’m trying to write a PoC for path traversal using hash extension attack on a php site.
My obstacle is in specifying an acceptable string. The vulnerability is in in the url:

I have a table where the machine name, directory path and filenames are stored; when requested, I am supposed to return the content of the file by concatenating the machine_name + ‘\’ + directory_path + ‘\’ + filename but thi… Continue reading Constructing file path from database table leading to vulnerability CWE 73: Directory Traversal
While trying to replicate a security vulnerability on my local machine I realized that PHP on my machine does not decode %2e as a dot. I created the following test-file:
<?php var_dump(file_exists(“%2e%2e/file_that_exists… Continue reading Conditions under which PHP path-traversal with %2e works
I am trying to add directory traversal vulnerability in php using Apache 2.2.17 server. I would like to test as http://localhost/test.php/../../../../../boot.ini request is made. However, I get 400 bad request and browser cou… Continue reading Prevent 400 bad request directory traversal
